  • Pause strategy for magnetic tape recording
    Publication number: 20060204209
    Abstract: A helical scan tape recorder (30) comprises a rotatable scanner (84) and a transport system for transporting magnetic tape proximate the rotatable scanner in a manner so that information is recorded during a revolution of the scanner. A controller performs a pause routine (120) for pausing during a recording operation on tape. The pause routine, when executed, performs the steps of: determining a tape pause position reference value indicative of a pre-pause last recording position on the tape; recording an erase signal on the tape after the pre-pause last recording position; rewinding the tape; transporting the tape in a forward direction and obtaining a current tape position value; determining when the current tape position value reaches a predetermined value relative to the tape pause position reference value; and at beginning of a next revolution of the scanner, commencing recording of one or more post-pause stripes on the tape.

  • Drum electronics control interface and protocol for recording/reproducing apparatus
    Patent number: 6870698
    Abstract: A method and apparatus for allowing communication between a stationary circuit and circuitry in motion with respect to the stationary circuit is presented. Communication is achieved and verified by transmitting a clock signal and a control signal in synchronization with the clock signal over separate clock and control transformer channels between the stationary circuit and the moving circuitry.
